HollerBot, the sub-$500 DIY robot

Zach Smith was tired of waiting for an affordable robot that did what he wanted it to do, so he's building his
own. And like any good geek, he's building it entirely out of off-the-shelf consumer hardware and free software,
all for less than $500. He also hopes to make it controllable via the Internet and able to communicate with the
real world, although we're not really sure exactly what else this thing is supposed to be able to do besides run around
tormenting people. Fortunately, that's good enough for us.
